Why Is Your Pond Losing Water

Why Is My Water Level Dropping?

We can probably rule out the baby emptying your pond! But lets have a look at some of the common causes of water loss.

Pond water levels dropping is a common problem that many pond owners come across and at first can seem quite worrying. Naturally, everybody’s first thoughts are “I have a leak in my pond” and “there must be a rip in the pond liner”. However, only about 5% of suspected leaks turn out to be leaks, so don’t panic just yet!

There are a few different reasons that could be causing the water levels to drop and we will go through them below so that you can diagnose what is causing your water to disappear.

Evaporation

This is the most common reason for water levels dropping although it may not seem possible as water levels can drop more than 1 inch per day. Depending on the time of year and where your pond is located in the garden, if it is exposed to long amounts of direct sunlight it is possible for significant amounts of water to evaporate.

Pond Plants

Depending on what plants you keep in your pond and what time of year they flower, this can also contribute highly to water loss. If you have plants that bloom during the summer months they will need to absorb high levels of water, couple this with the natural evaporation in summer months and it is easy to see how water levels can drop.

Splashes

If you have a waterfall, water feature or fountain pond pump in your pond setup, these could be the culprit to your disappearing water. If they are not perfectly aligned, they can splash or spray small amounts of water out of your pond. Spend a couple of minutes watching your waterfall, feature or fountain to see if you can see any obvious water splashes. If you see any splashes, adjust any rocks to direct water or change the flow rate to keep splashes to a minimum.

Leaking Pipework

Check all fastenings on pump pipework. These can sometimes be made of brittle plastic that overtime will degrade and possibly crack or split causing small leaks in pipework joints. If you do spot a leak around the filter box, try and diagnose where it is coming from and replace the part.

All the above reasons can contribute to the loss of water in a pond and unfortunately it is something that is likely to happen throughout the year. Where possible, top your pond up with water collected in a water butt, if this is not possible, use tap water. Either way, we recommend using Pond Equaliser to remove any harmful chemicals and stabilise the added water.
